This paper describes an experimental investigation of the skin depth effect for electromagnetic waves in salt water using a cell phone that is immersed to a critical depth where it no longer responds when called. We show that this critical depth is directly proportional to the theoretical skin depth for a range of salt concentrations.

Through the Internet of Things (IoT) people and devices are communicating and interacting with one another continuously. This includes devices such as thermostats, televisions, voice activated speakers (Amazon Echo), smartphones, tablets, and wearables (Fitbit). This is accomplished through the IoT using uniquely identifiable radio tags, sensors,…

Millennials: a generation always in the news--and not just in mainstream media but in the more powerful and influential news outlet, social media. This generation has attention unlike any before (at least not since the Baby Boomers), and it is changing our world in ways we have yet to fully realize. Millennials are challenging the norms of…

The use of digital technology has grown rapidly during the last couple of decades. During use, mobile phones and cordless phones emit radiofrequency (RF) radiation. No previous generation has been exposed during childhood and adolescence to this kind of radiation. The brain is the main target organ for RF emissions from the handheld wireless…

Developed by using ARKit, a novel app which can be used to detect position in physics experiments was introduced. The ARKit relies on a new technique. The result of the experiment presented in this study was satisfactory, suggesting that the new technique can be employed in position detection experiments/demonstrations that are conducted using…

Electromagnetic radiation is one of the most important issues affecting peoples' lives today. The misunderstanding of students and the general population of the effects of electromagnetic radiation is a problem which must be eliminated. Thus, a discussion about ionising and non-ionising radiation focusing on the crucial issue of radiation emitted…

When measuring the speed of an object with a video camera, a correction may be needed for the time taken by the camera to acquire the image in each frame. Examples are given where the correction is quite significant.

The sensors in modern smartphones are a promising and cost-effective tool for experimentation in physics education, but many experiments face practical problems. Often the phone is inaccessible during the experiment and the data usually needs to be analyzed subsequently on a computer. We address both problems by introducing a new app, called…

Augmented Reality (AR) has been used in various contexts in recent years in order to enhance user experiences in mobile and wearable devices. Various studies have shown the utility of AR, especially in the field of education, where it has been observed that learning results are improved. However, such applications require specialized teams of…

There are already several articles describing ways to teach physics using smartphone apps, but what are some experiments you can perform immediately without downloading any additional software? In the spirit of increasing the amount of hands-on activities each of us is doing, and to give us backup activities when you have a few extra minutes of…

Today, the mobile technologies and Information and Communication Technology development opened the door on new methods and pedagogies of learning. We are talking here about the mobile learning and the flipped classroom approaches. The flipped classroom means that the activities that have traditionally taken place inside the classroom now take…

This study examined the extent, motives and impact of mobile phone photo note-taking on students' learning at Dar es Salaam University College of Education (DUCE) in Tanzania. It employed the mixed methods approach. A sample of 310 respondents was drawn using a multi stage sampling technique which involved stratified random sampling at the first…

The internal sensors in smartphones for their advanced add-in functions have also paved the way for these gadgets becoming multifunctional tools in elementary experimental physics. For instance, the acceleration sensor has been used to analyze free-falling motion and to study the oscillations of a spring-mass system. The ambient light sensor on…

Technology can improve the educational experience of college students but also serves as a distraction both for students and those around them. This study applied marginal value theorem to the problem of cell phone use in the college classroom. 144 college students were placed in a simulated classroom and their technology use was observed and the…

Augmented Reality (AR) has gained significant attention in the field of language learning. This study conducted a systematic review of research on AR-supported language learning published between 2008 and 2022. Thirty articles were selected based on specific inclusion and exclusion criteria, and analyzed using an analytical framework with the…
